Padgett is absolutely correct. My car's VIN starts 11669B, from this you can tell it is a 1961 4-door sedan V8 Powerglide, assembled in Baltimore. Other numbers show it was built in April 1961. All the numbers, casting numbers, casting dates, engine stamps, even the carby tag, match. Nice There is no guarantee all this is correct, but the more corresponding data you have, the more certain you can be sure it is a "matching numbers" car. The diff code will be stamped on the rear axle housing, but I haven't got that far yet - it will be 3:08:1. This car lived all its life in WV until 2016 when it appeared in Adelaide, AU. It now resides in the fair city of Melbourne, in my garage, undergoing sympathetic restoration, hopefully to a B+ standard. It has zero options. A nasty made-in-China aftermarket radio went in the bin. No trunk light. One-speed wipers. Very basic, the way I like it. Why not drop in a 409, or at least a 348, you might ask: because it is only going to be original once: the cast iron PG runs fine and leaks next to nothing, and the 283 runs fast and smooth, clocked only 106k miles, oil nice and clean, barely run in, as a friend put it. Had one repaint some time ago, not very good, about 7/10, but I'm rubbing it back carefully now, and it is looking not bad. I had the original windscreen polished (all the glass is original), and I am now addressing the only significant rust at the ends of the front underbody brace, where mud accumulated over 55 WV winters. '61 4-door Chevys are becoming comparatively rare as many have been parted out to restore 2-door cars, and it was not a particularly high production year to start with.
My twilight turquoise and ermine white beauty is getting power brakes and power steering to make navigating around the 'burbs a tad easier, but that's all, and in any case these don't appear on the tags. The nasty aftermarket wheels (also made in China) will be replaced with 14x5 originals and correct 1961 hub caps. Everything else works fine after 59 years, and not a micro chip anywhere. Where is a Hyundai or for that matter a BMW going to be in another 59 years?
